Tags

You must enable the tagging of users and organizations in Zendesk Support for the API calls to work. In Support, click the Admin icon in the sidebar, select Settings > Customers, and enable the option.

JSON format

Tags are represented as JSON objects with the following properties:

Name	Type	Read-only	Mandatory	Description
tags	array	false	true	An array of strings

List Tags

• GET /api/v2/tags

Lists up to the 20,000 most popular tags in the last 60 days, in decreasing popularity.

Pagination

• Cursor pagination (recommended)
• Offset pagination

See Pagination.

Returns a maximum of 100 records per page.

Allowed For

• Agents

Limits

This endpoint has its own rate limit that is different from the account wide rate limit. When calls are made to this endpoint, this limit will be consumed and you will get a 429 Too Many Requests response code if the allocation is exhausted.

Headers

API responses include usage limit information in the headers for this endpoint.

Zendesk-RateLimit-tags-index: total={number}; remaining={number}; resets={number}

Zendesk-RateLimit-tags-index-pagination: total={number}; remaining={number}; resets={number}

Zendesk-RateLimit-tags-index-deep-pagination: total={number}; remaining={number}; resets={number}

Within this header, “Total” signifies the initial allocation, “Remaining” indicates the remaining allowance for the current interval, and “Resets” denotes the wait time in seconds before the limit refreshes. You can see the Total, and Interval values in the below table.

Details

This is the limit definition for the List Tags endpoint.

Rate Limits	Scopes	Interval	Sandbox	Trial	Default
Standard	Account	1 minute	100	100	2000
With High Volume API Add On	Account	1 minute	300	300	2000

"Default" applies to all Zendesk suite and support plans. Please refer to the general account limits for more information.

Count Tags

• GET /api/v2/tags/count

Returns an approximate count of tags. If the count exceeds 100,000, it is updated every 24 hours.

The refreshed_at property of the count object is a timestamp that indicates when the count was last updated.

Note: When the count exceeds 100,000, the refreshed_at property in the count object may occasionally be null. This indicates that the count is being updated in the background and the value property in the count object is limited to 100,000 until the update is complete.

Add Tags

• PUT /api/v2/tickets/{ticket_id}/tags
• PUT /api/v2/organizations/{organization_id}/tags
• PUT /api/v2/users/{user_id}/tags

You can also add tags to multiple tickets with the Update Many Tickets endpoint.

Safe Update

If the same ticket is updated by multiple API requests at the same time, some tags could be lost because of ticket update collisions. Include updated_stamp and safe_update properties in the request body to make a safe update.

For updated_stamp, retrieve and specify the ticket's latest updated_at timestamp. The tag update only occurs if the updated_stamp timestamp matches the ticket's actual updated_at timestamp at the time of the request. If the timestamps don't match (in other words, if the ticket was updated since you retrieved the ticket's last updated_at timestamp), the request returns a 409 Conflict error.

Example

{
  "tags": ["customer"],
  "updated_stamp":"2019-09-12T21:45:16Z",
  "safe_update":"true"
}
